Description
Technical field
The present invention relates to the preparation technology of battery, particularly a kind of welding method of lead accumulator bus-bar.
Background technology
Lead accumulator generally includes battery case, battery cover and is located at single or multiple utmost point group in the battery case, utmost point group comprises the positive and negative pole plate that multi-disc is mutual overlapping and is used for separating the demarcation strip of positive/negative plate, positive and negative pole plate top is provided with lug, each lug is connected with bus-bar by welding, and electric current is pooled on the motor terminal.Existing bus-bar welding manner mainly contains two kinds: a kind of for the pole plate short transverse perpendicular to ground, the pole plate lug adopts fuel gas manually to weld on top; Another kind be the pole plate short transverse perpendicular to ground, the pole plate lug adopts the equipment cast welding in the bottom.For artificial welding, owing to influenced by operating personnel's level, gas pressure etc., welding effect is not good, is easy to generate phenomenons such as rosin joint, mistake weldering, reduces battery performance; For the equipment cast welding, then need a large amount of scolders and scolder must be maintained molten condition, cause scolder to volatilize in a large number, cause that cost increases.
Summary of the invention
The problem that the present invention solves provides a kind of welding method of lead accumulator bus-bar, solves the problem that existing method welding bus-bar scolder is wasted easily, cost is high.
For addressing the above problem, the technical solution used in the present invention is:
A kind of welding method of lead accumulator bus-bar may further comprise the steps: the lug of each same sex pole plate of battery is fixed in the anchor clamps; In mold cavity, inject quantitative paste solder containing pb; Lug is immersed in the paste scolder; Fast Heating mold cavity to scolder melts; Cooling mold cavity certain hour makes scolder form the bus-bar that connects with the lug weldering fast, takes out bus-bar; Continue to carry out next group operation below the cooling mold cavity to 80 degree centigrade.
Further, described mold cavity adopts alloy material to make.
Further, described mold cavity adopts the intermediate frequency induction heating device heating, and its power is 5 kilowatts.
Further, the water cooling plant cooling around mold cavity is adopted in described quick cooling.
Further, be 5 to 8 seconds described quick cool time.
Compared with prior art, the advantage of technical solution of the present invention is:
By adopting the cast welding mode to form the lead accumulator bus-bar, and employing fast cooling shaping, when the mold cavity temperature is higher, take out lug when the molding, and then continuation cooling mold cavity, both guaranteed welding quality, also reduced the volatilization of scolder in high temperature, saved the consumption of scolder, reduced production costs.
Description of drawings
Fig. 1 is specific embodiment of the invention schematic flow sheet;
Fig. 2 is specific embodiment of the invention cast welding process schematic diagram.
The specific embodiment
The present inventor finds the existing method that adopts artificial welding lead accumulator bus-bar, waste time and energy, and efficient is low; And the method for employing cast welding, then when welding, cooling velocity is slow, easily causes scolder to volatilize in a large number, causes expense material, cost height and more serious to ambient influnence.
At the problems referred to above, the present inventor proposes a kind of technical scheme of solution, specifically as shown in Figure 1: execution in step S11: the lug of each same sex pole plate of battery is fixed in the anchor clamps; Execution in step S12: in mold cavity, inject quantitative paste scolder; Execution in step S13: lug is immersed in the paste scolder; Execution in step S14: Fast Heating mold cavity to scolder melts; Execution in step S15: cool off the mold cavity certain hour fast, make scolder form the bus-bar that connects with the lug weldering, take out bus-bar; Execution in step S16: continue to carry out next group operation below the cooling mold cavity to 80 degree centigrade.
The embodiment of the invention forms the lead accumulator bus-bar by adopting the cast welding mode, and employing fast cooling shaping, when the mold cavity temperature is higher, take out lug when the molding, and then continuation cooling mold cavity, both guaranteed welding quality, also reduced the volatilization of scolder in high temperature, saved the consumption of scolder, reduced production costs.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.
Fig. 2 is specific embodiment of the invention schematic diagram.As shown in Figure 2, at first, the lug 2 of each same sex pole plate of battery is fixed in the anchor clamps 1, just with special fixture that the lug of the same polarity of utmost point group is fixing neat.
Then, in mold cavity 3, inject quantitative paste scolder 6.Described paste scolder 6 is paste, can adopt and manually insert mold cavity, perhaps pumps into mold cavity by constant displacement pump.Described scolder 6 is lead alloy material, as lead-antimony alloy, lead-calcium alloy, and is added with scaling powder.Described scolder 6 keeps paste, in order to will immerse in the scolder 6 with the lug 2 that anchor clamps 1 fix.
After lug 2 immersed in the scolder 6, the described mold cavity 3 of Fast Heating made scolder 6 be melting state immediately.Described Fast Heating adopts intermediate frequency induction heating device 5 heating, and its power reaches 5 kilowatts, and firing rate is fast, and general needs heating scolder 6 can be melted in 15 to 25 seconds.
After scolder 6 melts fully, stop heating immediately, and adopt Cooling Mode, mold cavity is lowered the temperature.Water cooling plant 4 coolings around mold cavity are adopted in described quick cooling.When cooling off 5 to 8 seconds, the temperature of mold cavity has been cooled to 200 ℃ or following, and at this moment, bus-bar is moulding, takes out bus-bar.Because, when scolder 6 forms bus-bar in cooling, if directly be cooled to room temperature, very easily make bus-bar produce the cast welding defective, as crackle, crystalline particle is big, causes bus-bar and lug junction electric conductivity variation; Therefore, when bus-bar one moulding, and can the demoulding time, be about to it and take off, and under the state that cools off naturally, allow bus-bar inside finish last crystal moulding.Like this, on the one hand, improve the cast welding quality of bus-bar, on the other hand, also improved the operating efficiency of bus-bar cast welding.
After taking out bus-bar, continue the cooling mold cavity below 3 to 80 degrees centigrade, carry out next group operation.Described temperature is generally between 60 degrees centigrade to 80 degrees centigrade.Because mold cavity 3 temperature reduce, therefore, when injecting paste scolder 6 to it, volatilization can not take place and form bubble and cause follow-up cast welding to form defective in the scaling powder that adds in the scolder 6 and composition thereof, thereby guarantees the cast welding quality.
The described lead accumulator bus-bar of specific embodiment of the invention welding method, by adopting the cast welding mode to form the lead accumulator bus-bar, and employing fast cooling shaping, when the mold cavity temperature is higher, take out lug when the molding, and then continuation cooling mold cavity, make scolder very short in the time of melting state, reduced the volatilization of scolder in high temperature, and the volatilization of composition such as scaling powder, thereby guaranteed the cast welding quality, and effectively reduced the volatilization waste of scolder, reached the technique effect of saving cost, reducing the lead fume pollution.
Though the present invention with preferred embodiment openly as above; but it is not to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
